Lim, Wey Wen

Post-doctoral Fellow

Division of Epidemiology and Biostatistics

  • BSc (Hons), MPH, PhD

Dr Wey Wen Lim joined the School of Public Health, HKU as a Post-doctoral Fellow in 2022 shortly after graduating from the School with a PhD in epidemiology. She was trained as a biomedical scientist at the National University of Malaysia during her undergraduate study and obtained her Master of Public Health at our School in 2015.

Her doctoral research explored the link between vaccine immunogenicity and protection against infection or disease for influenza and COVID-19 with the use of established and novel correlates of protection, and investigated the impact of repeated influenza vaccination on vaccine effectiveness.

In her current research, Dr Lim examines the applications of correlates of protections in influenza and COVID-19 seroepidemiology, post-viral complications, and optimisation of vaccination strategies in pandemics.
